Question 3.

Option B is the correct answer. 

The author says "In a world where products and services often have to pass through regulatory hoops, large companies will usually have the advantage." From this, we can infer that the author doubts whether crafts can create substantial employment opportunities because smaller craft businesses may struggle to compete with larger companies due to regulatory barriers.

Option A: The passage does not focus on the low scale of crafts production as the primary obstacle. Instead, the author emphasizes regulatory challenges and not the scale.

Option C:  The passage does not argue that workers wouldn’t want to pursue crafts-related work, just that retraining them for these roles might be difficult.

Option D: The passage mentions that craft guilds resisted new entrants, but it does not suggest that they are unlikely to accept large number of trainees. The passage suggests that craft workers can thrive in the modern era, but the challenge lies in how modern crafts are organized and their potential to scale up in a competitive market.
